如何在Javascript中获得特定度数的椭圆的边缘坐标？

function getEllipseCoordinate(centerX, centerY, a, b, degree) {
  var angle = degree * Math.PI / 180;
  var x = centerX + (a * Math.cos(angle));
  var y = centerY + (b * Math.sin(angle));
  return { x: x, y: y };
}

// 示例用法
var centerX = 0;
var centerY = 0;
var a = 100; // 长轴长度
var b = 50; // 短轴长度
var degree = 45; // 目标度数

var coordinate = getEllipseCoordinate(centerX, centerY, a, b, degree);
console.log(coordinate);
